Specification of Letters A Patent No. 860, dated `.'I11`1y52`8, 1838.

`To all'whvom t may concern.' i A Be it known that I, JAMES WYMAn, of`Boston, in the county of Suffolk and State of Massachusetts, haveinvented a new and useful Machine for J ointingStaves for Barrels,Gasks, &c., whichis described as follows, reference being had to theannexed drawings of the same, making part of this-` speciiication.

A Figure '1, represents the frame of the `machine, made of sufficientsize and strength to contain and support the several parts of the,machine, hereafter described, Icomposed of six ports, mortised andtenoned into sills,

`or astout rectangular platform, two longitudinal caps, `and three crossties, Valso mortised and tenoned together. The two center posts risehigher than the top of the frame and are connected `together on top by atranverse cap a. t Y

B, B, two parallel ribs or ways fastened on top'of thelongitudinal'caps,at the inner edges thereof, over which the carriage moves.` y y c C,`the carriage formed of a rectangular shape being composed of kfourpieces of timber mortised `and tenoned, orgship lapped together, with alongitudinal piece c, mortised and tenoned, into the two end pieces inthe center thereof andparallel with the two side pieces, having. on theunder side of said center piece a rack d, Fig. l-into which a pinion eworks for moving the carriage forc ward, which is fixed on an horizontalaxle f, lying across the frame and revolved by certain gearing hereafterdescribed. On the top of this carriage are four blocks b-(One at eachcorner of the carriage, having `a groove cut lon the inside of each, forthe ends of guides to slide in hereafter described. Said grooves areformed by cutting the insideof each block obliquely from the upper Thegrooves, however,1 may be made rectangularly.-See Figs. 1, 2, and 7 Y D,D, two guides for moving the cutters to and fromI the stave in order togive it the required bilge or shape-the stave being fastened by dogs, orother suitable fastenings, on `the top of the center piece c, of thecarriage and the guides arranged parallel to said center piece-"with theends of the, guides placed in the groovesof theblocksl 1 beforedescribed-said ends being shaped to correspond with said grooves.` Each`guide 1s made concave on the front, or side toward the stave, .and ofa, correspondin','g'` i shape therewith, and straight on the opposite`side or back-See D Fig. 2. y

E, E, E, E, cutters for shapingthe stave-- the stavebeing moved betweenlsaid cutters. These cutters are made ,similarL 1to.plane irons as atuFig. 6 and are fastened to metallic stocks t' by screws-slotsbei'ng leftin the cutters to set them as desired and two or more cutters beingsecured toA each stock. The stocksY are` fastened onu inclined revolving4axles la, la, turned by pulleys ZJ, 'on said `axles and bands m,m1pas`sing around them to the main drum n Fig. l. Eachfaxle is Supportedby an oblong frame o, 0,(ofjthree y sidesthe long Aside .rest-ing``against the` guide by its gravity assisted by a spring p,

or weight and pulley ;-its lower short 'side` moving on a joint g `in ametallic box q resting on the center cross piece 05'?, ofvthe frame,near the center thereof said cutter frameV having an inclined positionthe same as the before mentioned axle. i Fig. 8. V t,

. The axle containing the cutters on one side of Vthe stave turns y inthe frame-the y See also lower end of said axle being brought to a vpoint and made to turn` in a cavity formed in the upper surface of thelower side of the frame atv-and its upper end in a cavity of aregulating box s-screwed into .the side of said cutter frame. Thisregulating box extends abovethe frame and moves in an oblong mortise t tmade in the cross cap of the main ,frame for guidingthe frame and Vcutters. The other frame, axle, and cutters are formed and arranged in asimilar manner, on the other side of the stave.`

F, Figs. 1 and 3, rack and bar for advancing to or receding from thecutterframe the concave guides in order to recede `from or advance thecutters toward the stave ac cording to the width of stave placed` there`on to be jointed. This is l, effected by fastening wedge shaped blocksfw Fig. 3 on the under side of said bar whichblocks as the bar is drawnforward come between inclined stops c Fig. 2 fastened on the top `of thecar`- riage and behind the concaverguide D, and of course cause theconcave guide to advance being contracted as the guide is advanced andextended as it is receded; said stops atl one end are staples insertedobliquely into the blocks b I) in which staples the ends of thespringsare inserted: those at the other end are pins.

The inclined frame with the cutters rest-i ing against the guide will,by its gravity,

fall back from the stave and against the guide, aided by its spring. Asimilar rackbarfF wedge shaped blocks fw, stops Vy and springs a tothose just described are arranged on the other side of the carriage foradvanc v ing and receding the other guide.

Both bars are drawn forward or pushed back, for causing the wedge shapedblocksy on the under side thereof to perform theirl oflice, by means oftwo pinions Gr, G, on a.y crank shaft U turning in boxes in the end; ofthe carriage by handsaid pinions working'into the racks H of the bars F.

rThe pinion e for advancing the carriage before mentioned is fastened onan axle f.

passing through one of the caps of the frame,'on the end of which axleis a bevel wheel `I into which works another bevel wheel J on the end ofan inclined shaft K having on its other end a cog-wheel M into whichworks a worm N on the end of the drum shaft S turning in boxes at theend of the frame. Y

The inclined shaft K turns in apertures or boxes in arms T projectingfrom the sides of the main frame. turning the cutters and advancing thecarriage is made of any required diameter and is turned by a band Qpassed around la small pulley V on the end of the drum leading to adriving pulley P on a crank axle R at the other end `of the Yframeturned by hand, or any other power.

The other end of the pinion axle f on which the bevel wheel is placedturns in the 'end of a lever L moving on a pin W inserted into the sideof the frame for putting the pinion into gear with the raclr*it is putinto gear by depressing the long end of the lever which raises the shortend with the pinion axle and when the pinion is in gear it isthus heldby means of a spring rest X. Fig. 4 fastened to the main frame whichspring rest is pushed from under the axle by the carriage strikingagainst its end VY when advanced as far as it is intended to The maindrum n forgo and the short end of the lever is pushed down with the axleby a spring g Fig. l which thus throws the pinion out of gear. Thecarriage is then brought back by the gravity of a weight it attached toacord j fastened to the carriage passing overV a pulley 0 at the endofthe main frame and then over another pulley t. l

To joint a stave in this machine it is firstto be secured in the centerof the carriage e by means of the dogs w lwthe pinions Gr at the end ofthe carriage are then turned which move the guides D by means of theracksY H, bars F, and wedge shaped blocks sition for jointingthe'stave'. The. pinion e isthen put in gear with the rack 0l of thecarriage Vcthe propelling power is then applied to the main axle R whichit turns with the main driving pulley P, which, by means of theconnecting belt Q, turns the main drum n and this turns the inclinedaxles 7c k and cutters E by thev bands m passing around it and saidpulleys Z Z of said axles. The carriage c with the stave N o. l nowadvances and the cutters being pushed out toward the stave as far asthey can Vgo by the convexity of the guides D, begin to cut the staveaway at the point, and as the carriage advances the frames() containingthe cutters recede from the stave by' following the 2 concavity of theguides causing the cutters to cut away the stave in'such a manner as togive it the required bilge bevel and taper which of course willcorrespond with the concavity of the guides; when the carriage hasadvanced as far as to bring the cutters in the greatest concavity thenthe greatest bilge will be vformed and now the cutters gradually cutaway more of it toward the other end Vby the gradual swelling of theguides toward the stave.

When the carriage has advanced as far as it is intended to go it comesin contact with the spring rest Y pushes it from under the pinion axlevY f which instantly falls and throws the pinion e out of gear with therack al by its gravity and the action of the spring g above the lever L.The carriage then runs backby the gravity of the weight hat the end ofthecord z fastened to the carriage c. The jointed stave is then removedand one not jointed secured in its place. The pinion is again put intovgear with the rack ofthe carriage and the operation is repeated in themanner just described.

VThe invention' claimed by me the said JAMES WYMAN, and which I desireto secure by Letters Patent consists- Y l. In the before Vdescribed modeof jointing staves by passing them between revolving cutters arranged inframes moving onk izo seo B the mannerl herein represented, or in anyother substantially the same in principle.
